Your new site is a great improvement on your old site. I'm sure it create a great response (and conversion rate) from customers and people who find the new site.
A few thoughts:
I might suggest to raise the font size or modify the font color for your main navigation menu, because it seems to get a little lost between the rotating images and the "trip-advisor" testimonial.
Make sure that when you push the new site live that you have a good permalinks structure so that the page urls would be more descriptive instead of the ?page_id=18 etc.
On the individual rental property pages, I would put a "call-to-action" button, or a link that allows users to request information/rent the specific property. Because right now when I'm on a property page (studio), if I "LIKE" that option, there's no option to pursue that option further.
On the page: http://188.8.131.52/~casadeka/?page_id=56
- It would be good to add some BOLD to parts of the text to help break it up and make it easier for the reader to read the content.
Just some thoughts after a quick glance at your good work... Hope it helps.
